[PATCH] video: fbdev: via: hide unused procfs helpers

[YueHaibing]

When CONFIG_PROC_FS isn't set, gcc warning this:

drivers/video/fbdev/via/viafbdev.c:1471:12: warning: ‘viafb_sup_odev_proc_show’ defined but not used [-Wunused-function]
 static int viafb_sup_odev_proc_show(struct seq_file *m, void *v)
            ^
fix this by adding #ifdef around it.
